- i To all whom t may concern Be it known that I, Joni: GHQPIESKA,

ecitiz'en of the United States, ijesiding at lattsmouth, in-the county of Cass and State of Nebraska, have invented a new and useful tPaeking-Ring for InternahCombustion Enl of which the following is a specification. 1

I .The present invention relates to improvementsinpacking rings for internal comring which'is provided with the necessary jhlresiliency and yet at the same time has no peripheml interstices that p'ermlt, of the f'pas'sage'of the gasses exteriorl'y of the 1318-" torr, .thus causing the maximum powento be '':f' Ie1-i'erted upon the piston and also permitting f the highest compression of the 0;

explosive charge within the cylinder.

-Ai fu'rther object of thepresent invention 1". is the provisionof'a sectional packin ring,

in which all of the various meeting e ges of prevent a direct passageway or channel the gases due to the compression or exstroke, thus providing a tight resilnt'at all times between the p ston and derfand guaranteeing the niaiiim'um l re-while the gas is being compressed,"

Patented Feb. 9, 1915.

In internal combustion engines it has been found desirable in order to secure the maximum power from the minimum mixture, to

employ a packing ring, which has the necessary resiliency and yet at the same time has no peripheral interstices that permit of the passage of the gases exteriorly of the piston, thus causing the maximum power .to be'exerted upon the piston during the explosive 'stroke and also permitting the highest compression of the explosive charge outwardly expanding ring 34;, the same be ing the innermost member of the packing ring as shown in Fig. 4.-

,The presenti'i-ng, consists of the internal ou'twardlyfexpanding member or ring-.4,

which is the innermost member of the-pres ent ring. lQisposed-about'the ring 4 is the sectional metallic ring 5, each section 6 of;

at when the ring is assembled to rovide i circumferential groove 8 for the reception of the sectional ring 9, the. sections 10 of which-ewe constructed similarly t'othe sections 6 oy the ring 5, the joints however being plac o alternate with the joints- Of the ring 5, q this means, the; wear upon the outer surfaiie l 4 5., of the sectional rings. 5 and 9y'is l ze 1nd Otlle i'obj I which is provided'with the ,oblique ends 7-,-

, thesections are so protected and disposed :as so c arly shown i Fi 3 hnd as the rings are formed of four or more sections, the same are permitted to be so i 1 expanded by the-spring ring 4, as 'to'cone form exactly to the walls of the' cylinde'r 1 1 and thus produce a tight resilient pecking between the piston and cylinder which will not have peripheral interstices and 'which' will'oe so tight as to preventthe passageof 7" the explosive charge beyond the ring during. the compression stroke 'or the exploded gases 7 beyond such packing ring upon the expl o s'ive stroke.

disposed as shownin Fig. 3 to project between the oblique ends of two adjacent secy I 7 {106 A pin 11 is carried by one section 6 and is tions 10 of the ring '9, and locks thesections of the entire ring-against-collapsing an also holds the sections of bothrin'gs fifa-n 93in fixed circumferential rel'ati'on.

positioned to permanentlyconnect one section of the ring 6 to one section of the'ring 9, thus providing va keystone locking means for locking the sections when-nested,

As shown in Fig. 5,- two rivets. lY-"ere lus beingicomposefi of a and also provides a better jointthan at pin 11 Fig. 3. In the use of .pin 11, should the same near loose, a port for the escape of compre "ion n'1ay"resuit, but when the rivets 11C are employed this is eliminated.

What is claimed is:

1. The combination with the cylinder of an explosion engine, and a power piston provided with a plurality ot circumferential pa'ckingring recesses, of a packing ring for each recess, including a main annulus havihga portion of its periphery recessed the full circumference thereof,-said main annulurality of segments, the meeting faces-o which are angularlydisposedrelative to the fiat faces of the annulus, a; second annulus fitting in the reces sed periphery of the main annulus with its .hod y :wgholly, lugithin the area. thereof, the annulus lieing composed of'a pluralitysof sections the' meeting faces of which arozangularly disposed relatively to the fiat wifaces of. they second, annulus I and sub tan- 1- it-ially at.right-anglesto-the meeting faces of thescctions of themain annulus, the rpeet- 'Tingfuces of one annulus being out of aliher ment. ivith thoseof-Hthc other, means for so;

curing one sectionv of each annulus ,tji'i'g'idly together, -and a single open.expandighgziring, nested uithin theinn-in annulus to holdthe sectionS3outWi1l'dlyj-tindresiliently in conmain annulus and tact with the inner face of the cylinder of the engine.

2. A packing ring, comprising a main annulus having a portion of its periphery 'recessed the full circumferential area thereof 3 said main annulus being composed of a plufaces of the sertious of the main annulus,

the meeting faces of one annulus being out of alinement with those of the' other, means piercing one section of each annul'u's for rigidly connecting suchsectionstogether-{ii sinring nested within the tting the? inner c rcumglo open expandin ference thereof. g
